Landslides
Landslides are downward and outward movement of slope materials
such as rock debris and earth, under the influence of gravity
-
Such movements may occur gradually, but sudden sliding can also
occur without warning.
Landslides often take place in conjunction with earthquakes, floods
Heavy landslides block the flow of rivers for quite some time, which
on bursting can cause havoc to human settlements downstreanm
Avalanches are a mass of snow, ice, and rocks falling rapidly down a
mountainside

Landslide prone areas of India
The hilly terrains of India, particularly in the Himalayas and the
Western Ghats, are most vulnerable to landslides.
The Himalayan mountain belt comprises of tectonically unstable
younger geological formations and often the slides are huge
Threat of landslides to
housing and infrastructure, farms and fields,
-. vast stretchesofborder roads and railway lines,
hydro-electricand watersupply installations,
-transmission line pojects,
tunnels, heritage buildingsand monasteries,
pilgrim routes, and tourist spots
_

Causes
Heavy rain - The main cause of landslides
Deforestation
Earthquakes and volcanic explosions
Building of roads
# Construction of houses and other buildings

Landslide Management
Landslides, unlike other natural disasters, occur as isolated incidents
and hence have to be treated individually.
Management is confined to ad-hoc solutions ofsite specific problems
Eg: Implementationofimmediate remedial measues like debris removal
Remediation practices, like
0 Slope geometry correction
providing protection to the toe of slope by retaining structures,
Management of the surface and sub-surface water including the
development of pore pressures, nailing
